Solution 1

After reading your post, I just noticed pretty much the same thing. Might be that their server is down for a bit.

Solution 2

I had the same problem and i fixed this issue by setting my ISP's DNS adress manually on /etc/resolv.conf (that is probably another issue why i had dns as 192.168.0.254 from dhcp) Rafael, might you have same issue?

Solution 3

Ubuntu. Arrrghhh. The answer you are looking for is somewhere. Does that help?

sudo apt update --option Acquire::Retries=100 \
                --option Acquire::http::Timeout="60"

It seems like Launchpad is down...

[Alvar]

This answer may help. I suggest you choose another server. Stuff like this happen form time to time.

[Lekensteyn]

@TheEvilPhoenix: DNS is a valid issue, if the DNS server you're using returns a wrong IP or if a firewall is blocking it altogether, such an error may occur. Think a bit out of the box, otherwise it could be closed as "too localised" ;)
